I just got a dBm meter(HP 400EL), & I'm messing with a mixer input channel. The manual says the meter is calibrated to dBm, and will only be accurate with a 600 ohm load. So...I put in a test signal to the input transformer, which is 600:600, should I be reading dBm at the output of the xformer? If I test the output of the module unbalanced, do I need to add a 600 ohm load to get a correct reading? If I check levels at the input of one of the amp cards on the module, which all have a 604R from input to ground, I'm guessing I'll get a good reading, yes?
Thanks,
Thanks,
